The ancient Romans were known for their advanced culinary techniques, and their kitchens often incorporated a built-in steam room. These steam rooms, known as 'laconica,' were used for various purposes, including cooking and bathing. The Romans believed that steam had therapeutic properties and used it to cook food, as well as for relaxation and cleansing. The steam rooms in ancient Roman kitchens were typically made of stone or brick and featured a central heating system that produced steam. The steam would then circulate throughout the kitchen, providing a moist and warm environment for cooking. This innovative feature allowed the Romans to prepare meals using steam, which helped retain the natural flavors and nutrients of the ingredients. Additionally, the steam rooms provided a luxurious bathing experience for the residents of the Roman household.
